Di Nitto <fdinitto(a)redhat.com> Date: 2018-01-08 (Mon, 08 Jan 2018) Changed paths: M libknet/threads_common.c Log Message: ----------- [PMTUd] only notify PMTUd when pmtud_running and don't force a run to avoid lock fighting When we request a writelock, we should notify PMTUd to abort and cond_signal only if PMTUd is running. Also, don't request an immediate rerun as we cannot guarantee that the scheduling is favourable to our request and we could end up waiting forever. Signed-off-by: Fabio M.
